Printing from a handheld device via a remote server

ABSTRACT

Systems and methods are provided though which a transaction, e.g., in a multi-tier, distributed application may be initiated from a portable or hand-held device, such as a smartphone. A computer system or systems, possibly remote from the device, may approve the transaction, complete it, or both, and the remote computer system or systems may cause a document to be printed, e.g., by a printer physically proximate to the device. 
     Aspects of the invention are illustrated by embodiments in which a drug prescription may be created electronically using a hand-held device. In such an embodiment, the prescription may be transmitted to one or more remote computer systems, such as an application server, for processing. If specified, the remote computer systems may cause a prescription to be printed, e.g., at a printer near the prescriber&#39;s location. The prescriber may sign the printed prescription and give it to a patient or pharmacy.

BACKGROUND

Handheld electronic devices may process, store, and retrieve data, whichthey may share using voice and/or data networks. They may thereforeserve as platforms upon which applications may be created for variouspurposes. Mobile telephones that include such capability, or“smartphones,” have enjoyed great popularity.

Handheld devices may nonetheless be limited in ways that other dataprocessing devices, including, for example, portable computers, are not.One such limitation is that such devices may provide, at best, limitedsupport for printing and may often provide no support for printing atall. Such limits may reflect factors that may include, for example, therelatively limited storage and processing capabilities of handhelddevices and the difficulty of associating a printer with a device thatmay be carried and used nearly anywhere and any time, among many others.

BRIEF SUMMARY OF THE INVENTION

Embodiments of the invention provide systems and methods for initiatinga transaction, which may include printing of a document, from a handhelddevice. In an embodiment of the invention, a user of a device mayinitiate printing of a document, e.g., from within an application on thedevice. The application may cause the device to transmit information,e.g., in the form of one or more queries, to a server, which may bephysically remote from the device, the printer that will be used, orboth.

The server may process and/or store some or all of the transmittedinformation, which may include processing that is not directly relatedto the printing operation. The server may identify a printer that is toservice the printing request, and in an embodiment of the invention, theserver may use information about the physical and/or logical location ofthe device to select the printer. The server may then transmitinformation to the printer and/or a server associated with the printerto cause the printer to service the print request.

Embodiments of the invention may relate to the electronic prescribing,e.g., of medication, by a health care professional, such as a physician.(For the sake of convenience, a person creating a prescription inconnection with an embodiment of the invention may be referred to simplyas a “physician,” but it will be appreciated that depending, e.g., onthe jurisdiction, a drug may be prescribed by a health care providerother than a physician. Unless otherwise required by the context, areference to a physician in connection with an embodiment of theinvention may include such other provider.)

Electronic prescribing may provide several advantages, including, forexample, automatic checking for drug interactions and/or insurancecoverage, automatic updating of a patient's chart and/or other records,and making drug information readily available at the time ofprescription, among others. An electronic prescribing applicationaccording to an embodiment of the invention may be created for ahandheld device, e.g., such as referred to above. In an embodiment ofthe invention, a physician may create a prescription electronically,which may then be transmitted, e.g., to a server, which may thentransmit information to a printer to cause a paper prescription to beprinted. The paper prescription may then be signed by the physician.

In an embodiment of the invention, medical information (which mayinclude information about payment and/or insurance or other coverage formedical products and/or services) may be available to a user of ahandheld device through an application. The application may similarlysupport printing of such information via a server. In an embodiment ofthe invention, the selection of the destination printer may varydepending, e.g., on the type of information to be printed.

In an embodiment of the invention, a method is provided of printing adocument, in response to a request from a handheld device, in connectionwith a computer system that comprises one or more processors, one ormore interfaces operatively coupled to at least one of the processors,and one or more databases operatively coupled to at least one of theprocessors. The method comprises receiving from the handheld device,through one or more of the interfaces, one or more queries comprisinginformation related to a transaction; approving the transaction based onthe information comprised by the queries; selecting a printing systembased on the information comprised by the queries; and transmitting tothe selected printing system, though one of the interfaces, informationsufficient to cause the printing system to print a document that isrelated to the transaction.

In an embodiment of the invention, at least one of the queries compriseslocation information specifying the location of the handheld device, andselecting a printing system comprises selecting a printing system basedon the location information. In embodiments of the invention, theprinting system, the handheld device, or both of them are physicallylocated remotely from the physical location of the computer system.

In an embodiment of the invention, the transaction is a prescription fora drug. In one such embodiment, the drug is a controlled substance; andthe document is a written prescription for the drug in a form forsignature by a prescriber.

In an embodiment of the invention, the method comprises generating arepresentation of the document in a page description language, whereinthe transmitted information comprises the generated representation ofthe document.

Embodiments of the invention include computer systems configured tocarry out the above methods and computer-readable media encoded withinstructions that, when executed by one or more processors within acomputer system, cause the computer system to carry out those methods.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

A description herein of one or more embodiments of the invention mayrefer to a handheld device. The term “handheld device” may be usedherein to refer to any such device, which may be, e.g., easily portable,powered from an internal source, intended for use while the usersupports the device in one or both hands, and capable of sending andreceiving information, e.g., wirelessly via one or more voice and/ordata networks. For brevity, an application (such as, e.g., a softwareapplication) for use on a handheld device may be referred to herein as a“handheld application.”

It will be appreciated that an application, operating on the handhelddevice to process information, may use one or more facilities providedby the hardware and/or software of a handheld device to causeinformation to be transmitted from the handheld device. Similarly,information may be received by the handheld device and, e.g., madeavailable to an application by one or more facilities provided by thehardware and/or software of the handheld device. For brevity, suchoperations may be referred to simply as transmission and reception ofinformation, respectively, by the application.

Embodiments of the invention may be practiced in connection with one ormore programmable digital computers. FIG. 1 is a block diagram of arepresentative computer system 140 such as may be used in connectionwith an embodiment of the invention.

The computer system 140 includes at least one processor 145, such as,e.g., an Intel Core™ 2 microprocessor or a Freescale™ PowerPC™microprocessor, coupled to a communications channel 147. The computersystem 140 further includes at least one input device 149 such as, e.g.,a keyboard, mouse, touch pad or screen, or other selection, pointing,and/or input device, at least one output device 151 such as, e.g., a CRTor LCD display, a communications interface 153, a data storage device155, which may comprise, e.g., a magnetic disk, an optical disk, and/oranother computer-readable storage medium, and memory 157 such asRandom-Access Memory (RAM), each coupled to the communications channelor bus 147. The communications interface 153 may be coupled to a networksuch as the Internet.

A person skilled in the art will recognize that a computer system mayhave multiple channels 147, which may be interconnected. In aconfiguration comprising multiple interconnected channels, componentsmay be considered to be coupled to one another despite being directlyconnected to different communications channels. Additionally, anyconnection between or among any one or more components may include oneor more interfaces.

One skilled in the art will recognize that, although the data storagedevice 155 and memory 157 are depicted as different units, the datastorage device 155 and memory 157 can be parts of the same unit orunits, and that the functions of one can be shared in whole or in partby the other, e.g., as RAM disks, virtual memory, etc. It will also beappreciated that any particular computer may have multiple components ofa given type, e.g., processors 145, input devices 149, communicationsinterfaces 153, etc.

The data storage device 155 and/or memory 157 may store instructionsexecutable by one or more processors 145 or kinds of processors, data,or both, which may represent, e.g., one or more operating systems,programs, and/or other functions and/or data.

FIG. 2 is a simplified block diagram that illustrates functionalcomponents that may be found in a handheld device 180, in connectionwith an embodiment of the invention. Functions in a handheld device maybe controlled, e.g., by a programmable applications processor ormicrocontroller 190. Memory 194 coupled to the applications processor190 may include one or more kinds of persistent and/or volatile memoryand may store, e.g., instructions to be executed by the applicationsprocessor 190 and/or data upon which the applications processor 190 mayoperate, which may represent, e.g., one or more operating systems,programs, and/or other functions and/or data, among other things.

One or more input devices 198 may be coupled to the applicationsprocessor 190, e.g., directly and/or via one or more input controllers202. Examples of input devices 198 may include, among otherpossibilities, one or more buttons and/or switches (which may includebuttons or switches configured as one or more keypads and/or keyboards),touchscreens, proximity sensors, accelerometers, and/or photosensors.

One or more output devices, including, e.g., one or more displays 206,may be coupled to the applications processor 190, e.g., directly and/orvia one or more output controllers 210. A handheld device 180 may outputinformation in ways that do not involve a display 206, e.g., bycontrolling illumination of one or more LEDs or other devices.

In a handheld device 180, which may be, e.g., a device capable of actingas a telephone, the input devices 198 and output devices 206 may includedevices configured to detect and/or emit sound (not pictured).

A handheld device 180 may comprise a camera 214 capable of recording,e.g., still and/or moving pictures. As depicted, the camera 214 may becoupled to the applications processor 190.

The handheld device 180 may be powered, e.g., by one or more batteries218. The applications processor 190 and/or other components may bepowered, e.g., via a power management unit 222 coupled to the battery218. If the battery 218 is rechargeable, the power management unit 222may monitor and/or control charging and/or discharging of the battery218. Power to charge the battery 218 may be supplied, e.g., via one ormore external ports 226.

A handheld device 180 may include one or more external ports 226 thatmay support analog and/or digital input and/or output.

A handheld device 180 may be configured to participate in one or morelocal area networks (LANs). For example, as FIG. 2 depicts, a handhelddevice 180 may include one or more transceivers 230 supporting, e.g.,Bluetooth® and/or Wi-Fi™ networking. Such a transceiver 230 may beconnected, e.g., to one or more antennas 234 and, as FIG. 2 depicts, maybe coupled to the applications processor 190.

A handheld device 180 may be configured to interact with one or morewide-area networks (WANs), such as, e.g., cellular voice and/or datanetworks. For example, as FIG. 2 depicts, a handheld device may compriseone or more cellular transceivers 238 and associated antennas 242. Atransceiver 238, as in the depicted device 180, may be coupled to adevice such as a communications processor 246, which may includefunctions such as, for example, of a digital signal processor and/or amicrocontroller. A communications processor 246 in a handheld device 180may also be coupled directly or indirectly to the applications processor190.

A handheld device 180 may include a unit 250 that is capable ofreceiving and/or interpreting signals from the Global Positioning System(GPS). The GPS receiver 250 may be coupled to its own antenna 254. TheGPS receiver may also be coupled in a handheld device 180 to theapplications processor 190, the communications processor 246, or both.

It will be appreciated that FIG. 2 and the discussion of it herein arenot meant to describe precisely any particular device, but rather toillustrate functions that may commonly be found in certain classes ofdevices. A handheld device suitable for use in connection with anembodiment of the invention may differ in its physical or logicalorganization from the depicted device, and such a device may compriseone or more other components in addition to, or instead of, any one ormore discussed or depicted components.

FIG. 3 depicts elements of wired and wireless networks 300 such as,e.g., one or more computers, handheld devices, or both, may use tocommunicate in connection with an embodiment of the invention. A network304 may, for example, connect one or more workstations 308 with eachother and with other computer systems, such as file servers 316 or mailservers 318. The connection may be achieved tangibly, e.g., via opticalcables, or wirelessly.

A network 300 may enable a computer system to provide services to othercomputer systems, consume services provided by other computer systems,or both. For example, a file server 316 may provide common storage offiles for one or more of the workstations 308 on a network 304. Aworkstation 312 may send data including a request for a file to the fileserver 316 via the network 304 and the file server 316 may respond bysending the data from the file back to the requesting workstation 312.

The terms “workstation,” “client,” and “server” may be used herein todescribe a computer's function in a particular context, but anyparticular workstation may be indistinguishable in its hardware,configuration, operating system, and/or other software from a client,server, or both. Further, a computer system may simultaneously act as aworkstation, a server, and/or a client. For example, as depicted in FIG.3, a workstation 320 is connected to a printer 324. That workstation 320may allow users of other workstations on the network 304 to use theprinter 324, thereby acting as a print server. At the same time,however, a user may be working at the workstation 320 on a document thatis stored on the file server 316.

The terms “client” and “server” may describe programs and runningprocesses instead of or in addition to computer systems such asdescribed above. Generally, a (software) client may consume informationand/or computational services provided by a (software) server.

The term “printing system” may be used in a broad sense herein to referto, e.g., a printer, or a print server and one or more associatedprinters, configured such that a computer system may send documentsand/or commands to the printing system, which may in response print oneor more documents or cause one or more documents to be printed by one ormore of the printers that the printing system comprises. For example,referring to FIG. 3, “printing system” may refer to the printer 324 orto the combination of the workstation 320 (insofar as it operates as aprint server) and the printer 324.

A network 304 may be connected to one or more other networks 300, e.g.,via a router 328. A router 328 may also act as a firewall, monitoringand/or restricting the flow of data to and/or from a network 300 asconfigured to protect the network. A firewall may alternatively be aseparate device (not pictured) from the router 328.

Connections within and between one or more networks may be wired orwireless. For example, a computer or handheld device may participate ina LAN using one or more of the standards denoted by the term Wi-Fi™ orother technology. Wireless connections to a network 330 may be achievedthrough use of, e.g., a device 332 that may be referred to as a “basestation”, “gateway”, or “bridge”, among other terms.

A network of networks 300 may be referred to as an internet. The term“the Internet” 340 refers to the worldwide network of interconnected,packet-switched data networks that uses the Internet Protocol (IP) toroute and transfer data. A client and server on different networks maycommunicate via the Internet 340. For example, a workstation 312 mayrequest a World Wide Web document from a Web Server 344. The Web Server344 may process the request and pass it to, e.g., an Application Server348. The Application Server 348 may then conduct further processing,which may include, for example, sending data to and/or receiving datafrom one or more other data sources. Such a data source may include,e.g., other servers on the same network 352 or a different one and/or aDatabase Management System (“DBMS”) 356.

Depending on the configuration, a computer system such as theapplication server 348 in FIG. 3 or one or more of its processors may beconsidered to be coupled, e.g., to the DBMS 356. In addition to orinstead of one or more external databases and/or DBMSs, a computersystem may incorporate one or more databases, which may also beconsidered to be coupled to one or more of the processors within thecomputer system.

Devices, including, e.g., suitably configured handheld devices andcomputers, may communicate with Internet-connected hosts. In such aconnection, the device may communicate wirelessly, e.g., with a cellsite 360 or other base station. The base station may then route datacommunication to and from the Internet 340, e.g., directly or indirectlythrough one or more gateways 364 and/or proxies (not pictured).

A handheld device may be capable of storing and/or executing one or moreapplication programs (or “applications”). In an embodiment of theinvention, an application may provide, e.g., information about one ormore patients to a user, who may be a health-care professional such as aphysician. Such an application may further assist the user in providinghealth care, e.g., by allowing the user to add or modify information,send messages, and/or order laboratory tests, among other functions.

An application may also allow a user to prescribe medicationelectronically. FIG. 4 depicts a workflow 400 for creating aprescription according to an embodiment of the invention. In block 410,the prescriber may enter the workflow by accessing a summary of thepatient's chart. Precisely how to access a particular patient's summarymay vary depending on the application.

In an embodiment of the invention, a user may have one or more ways torecall a patient's summary. One such way, for example, may be to searchfor a patient by name. In one application, in connection with anembodiment of the invention, a search display 430, e.g., as in FIG. 5,may include a text entry field 434. The user may enter all or part of apatient's name in the text entry field 434 and then initiate the search,e.g., by selecting a control 438 labeled “Go” or “Search”. A list ofmatching patients' names 442 may then appear, e.g., as in a display 450such as FIG. 6 depicts, and the user may select the intended patientfrom the list 442.

Other ways for a user to recall a patient's summary in an embodiment ofthe invention may include, among others, selecting an icon or othercontrol (not pictured) while viewing information related to the patient,e.g., a notification or alert related to the patient or a result for alab test related to the patient. An application may, in connection withan embodiment of the invention, maintain a list, e.g., offrequently-accessed or “favorite” patients, and the user may select apatient from such a list (not pictured).

In response to the user's selection, summary information for the patientmay appear. FIG. 7 depicts a display 480 of summary information for afictitious patient according to an embodiment of the invention. Asdepicted, the summary information may include, for example, thepatient's name 484, date of birth 488, age 492, and sex 496. Selectionof an information button 500, may cause display (not pictured) of thepatient's demographic information, such as, e.g., address, telephonenumber, chart identifier, etc.

A search icon 504 may be provided, which may allow the user to searchfor another patient.

In the depicted application, the patient's chart, when first displayed,may list laboratory results 508 for the patient, but other informationand/or functions may be available. For example, in an embodiment such asFIG. 7 depicts, a gesture may move the display left or right and replaceit with a display (not pictured), e.g., of allergies, activemedications, notes, and/or other information.

In an embodiment of the invention, a user may write a prescription fromthe patient's active medication screen 540, e.g., as FIG. 8 depicts. Asdepicted, the screen 540 displays a list 544 of recently-prescribedmedications 548, 552 for the patient. To write a new prescription fromthis screen 540, the user may then select “New Rx” 556.

In response to the selection of “New Rx” 556, a prescription screen 580may be displayed, e.g., as in FIGS. 9a and 9b . From the prescriptionscreen 580, the user may create the prescription, e.g., by selecting orotherwise specifying attributes of the prescription in blocks 412, 414,416, and 418 of FIG. 4. The prescription screen 580 of FIGS. 9a and 9bmay, for example, allow the user to select a delivery option, a pharmacy590, and a medication 594.

In block 412 of FIG. 4, according to an embodiment of the invention, theuser may select a delivery option, which may include selecting apharmacy to which the prescription may be sent electronically. In thedepicted embodiment, the user may specify the delivery method byselecting the currently-selected pharmacy 590 from the screen 580 inFIG. 9a . As a result, the user may be presented with a pharmacyselection screen 620, e.g., as FIG. 10 depicts.

In an embodiment of the invention such as FIG. 10 depicts, the user ispresented with delivery options that include “Sample” 630, “Mail Order”634, and “Auto-Print” 638.

In an embodiment of the invention, the “Sample” 630 delivery option maymean, e.g., that a prescription record may be, e.g., created and storedwith the patient's chart, but that no electronic prescription will becreated. One use for this delivery option may occur when a physiciandispenses a sample of the prescribed medication directly to the patient.Also, the “Sample” 630 delivery option may be chosen if a prescriptionis delivered, e.g., as a handwritten prescription on a blankprescription form.

Reflecting these applications of the “Sample” 630 delivery option, in anembodiment of the invention, if the “Sample” 630 delivery option isselected, the “Send” button 606 (FIG. 9a ) may be disabled, leaving the“Save” button 602 (FIG. 9a ) as the only active control allowing theuser to process the prescription.

The “Mail Order” delivery option 634 may in an embodiment of theinvention indicate that the prescription will be submittedelectronically or faxed to a mail order fulfillment center thatprocesses and mails the medication(s) to the patient's home address. Apatient's chart may indicate the mail order fulfillment center that isassociated with the patient directly or indirectly, e.g., by identifyinga mail-order pharmacy associated with a pharmacy benefits manager(“PBM”) that may administer a prescription plan in which the patientparticipates. If a patient's chart indicates that the patient isassociated with more that one mail order fulfillment center, the user inan embodiment of the invention may select which center is to receive theprescription. A record for a mail order fulfillment center may beassociated with information specifying how an electronic or facsimileprescription may be delivered to that fulfillment center.

The “Auto-Print” 638 delivery option in an embodiment of the inventionmay allow a user to enter a prescription, e.g., electronically using anapplication on the handheld device, but have a paper prescriptionprinted automatically, which the prescriber may then sign and deliver tothe patient. In an embodiment of the invention, as discussed below, oneor more printers may be associated, e.g., with respective locations.When the “Auto-Print” 638 delivery option is selected, the user'scurrent location may be used to set a default choice of printer for theprescription. In an embodiment of the invention, the user may be able tooverride the default assignment of a printer, e.g., by selecting aparticular printer from a list (not pictured).

To choose a pharmacy as a delivery option, the user may in an embodimentof the invention select a pharmacy from a list presented in the pharmacyselection screen 620. The list may be populated, for example, withpharmacies that the user has recently sent prescriptions to.

In an embodiment of the invention, the user may search for a pharmacyother than one listed, e.g., by entering in a text field part or all ofthe name, telephone number, address, postal or ZIP code, or otherattribute of the desired pharmacy. In an embodiment of the invention,the application on the handheld device may transmit the search as aquery, e.g., to a server, which may execute the search against one ormore databases and then transmit the results to the handheld device,e.g., as a response to the query. Pharmacies that satisfy the query, ifany, may be presented to the user, e.g., in a list (not pictured), andthe user may select the desired pharmacy.

Returning to the flow of FIG. 4, the user may select a medication toprescribe in block 416. FIG. 11 displays a medication selection screen700 that an application on a handheld device may display to a user in anembodiment of the invention. The depicted screen 700 displays a list 720of entries 724 that correspond to drugs recently prescribed by the user.For example, the depicted screen 700 includes an entry 728 for Adipostand an entry 732 for Advair® Diskus®.

In an embodiment such as FIG. 11 depicts, an entry 732 for a drug mayinclude a header 736 that begins the entry. The entry may include one ormore items 740 that may represent prescriptions for the named drug withdetails such as dosage, form, amount, etc., already supplied. Each suchitem 740, for example, may correspond to the details of a prescriptionthat the user has recently written.

An entry 732 may also include a blank item 744, which may, when selectedin an embodiment of the invention represent mere selection of a drug toprescribe, leaving the other details of the prescription blank for thetime being.

The medication selection screen 700 may include a text field, in anembodiment of the invention, in which the user may enter a partial orcomplete drug name and search for possibly matching drugs. As elsewhere,the search term may be transmitted, e.g., to a server, as a query, andthe server may return, e.g., as a response to the query, a list ofdrugs, if any, that match the search term. The application may thenpresent a list (not pictured) of matching drugs to the user, who mayselect the one intended for prescribing.

After selecting the medication, the user in an embodiment of theinvention may supply and/or edit additional details of the prescriptionin block 418 of FIG. 4. For example, in an embodiment of the invention,additional details may include one or more of: the form of the drug; theroute of administration; the amount of the dose; the frequency withwhich the drug is to be administered; the number of units to bedispensed; the number of days for which the patient is to take the drug;the number of refills, if any; whether the prescription is to bedispensed as written (“D.A.W.”); any notes to be transmitted to thepharmacy; and any notes, e.g., for the patient's chart, that are not tobe transmitted to the pharmacy.

If the user selected an item 740 such as in FIG. 11, in an embodiment ofthe invention, some or all items of additional information may receivevalues such as may have been provided, e.g., in the correspondingprevious prescription. In that case, the user in block 418 of FIG. 4 maychange or supplement the previously-supplied information. If the userselected only a drug in block 416 of FIG. 4, however, the user may thensupply such additional information in the first instance in block 418.

An application may provide appropriate user interface elements, e.g.,such as are known in the art, for entry of additional information. Forexample, FIG. 12 depicts a strength and dose form selection screen 760according to an embodiment of the invention. It will be appreciated thatother user interface elements and/or arrangements may be used in anembodiment of the invention to obtain prescription information from auser.

In an embodiment of the invention, a user may save a prescription inprogress or a completed prescription to a patient's chart, e.g., to becompleted and/or transmitted later. In an embodiment of the invention,when the selected delivery option is “Sample”, the electronicprescribing process may end with saving the completed prescription tothe patient's chart.

In an embodiment of the invention, a user may be presented with otherinformation related to the prescription, including for example,information related to the cost of the prescription and/or payment forit. For example, in an embodiment of the invention, formularyinformation may be presented (not pictured), e.g., regarding paymentinformation provided by a prescription plan in which the patientparticipates. Formulary information may comprise identification of oneor more drugs similar to the selected drug and/or approved for one ormore of the same indications as the selected drug and paymentinformation related to the identified drug or drugs. For example, if therelevant payer does not cover the selected drug (i.e., the drug is noton the formulary applicable to the patient), the information mayidentify one or more drugs that are on the formulary that may in somecircumstances be prescribed instead of the selected drug. Formularyinformation may also comprise, e.g., limit or requirements imposed bythe payer for the selected medication.

In an embodiment of the invention, information about drug pricing by theselected pharmacy may be available electronically, and in an embodimentof the invention, this pricing information (not pictured) may bepresented to the user.

In block 420 of FIG. 4, the user may submit a prescription, e.g., fortransmission to a printer, fax machine, and/or retail or mail-orderpharmacy. In an embodiment of the invention, For example, in anembodiment such as FIGS. 9a and 9 b depict, a “Send” button 606 may beprovided that, when selected, causes the application on the handhelddevice to transmit one or more queries from the handheld device thatinclude information making up the prescription and/or associated withit. As discussed below, the prescription may be processed by the serverand then transmitted, e.g., for printing and/or electronic delivery. Ifprocessing is successful, the server may transmit, e.g., a response tothe query or queries to the application on the handheld device, whichmay present, e.g., a confirmation message (not pictured).

If the “Auto-Print” delivery option was selected, in an embodiment ofthe invention, the confirmation message may indicate that a paperprescription has been printed at the selected printer. In block 422, theuser may retrieve the printed prescription, sign it, and then deliverthe signed prescription to the patient.

In embodiments of the invention, a prescription, once created, may berefilled and/or modified, e.g., from the patient's chart. A user mayreceive an alert (not pictured), generated, e.g., by an application onthe handheld device according to an embodiment of the invention, when aprescription is to be renewed. Such an alert may be generated, e.g.,automatically by the application or a server communicating with theapplication based on the record of the original prescription in thepatient's chart. An alert may be generated in other ways, e.g., by arequest from a pharmacy for authorization to renew or refill theprescription, or by a manual entry in an application on the handhelddevice, on another client-side device, and/or a server-side application,which may indicate, for example, that a renewal may be needed orrequested.

In an embodiment of the invention, one or more of the servers discussedherein may be in some sense remote from one or more of the handhelddevice, printer server, and printer. “Remote” is used in the ordinarysense herein, and may indicate that one device is located in a facilitythat is commonly considered separate from the facility containinganother device. For example, printers and print servers may commonly beconfigured to communicate only with devices connected to the same LANand/or one or more physically proximate bridged networks, which maycommonly span a single facility. A device such as a server may beconsidered remote, according to an ordinary use of the term, if, forexample, it is located beyond the ordinary physical bounds of suchnetworks.

A very large structure may be considered to comprise multiplefacilities, and two devices may be considered remote despite beingphysically located within the same structure. For example, a medicalcenter such as a hospital may comprise private practice groups in onepart of a relatively large building or complex. A server, e.g., in acomputer room, located in a part of the building apart from the spaceoccupied by the practice groups such that an employee of the practicegroup would be unlikely to come near the server in the ordinary courseof work in the practice group, may be remote from a device within thespace occupied by the practice group.

FIG. 13 depicts processing. e.g., by one or more servers incommunication with a handheld application according to an embodiment ofthe invention. The flow that FIG. 13 depicts may assume that the user ofthe handheld device has already created an account or is otherwise in arelationship with a service provider who operates the server. Some formof communications session may already have been established between thehandheld application and a server, which may have involved, e.g., theuser, device, and/or application providing identification and/orauthentication to the server. It will also be appreciated that some orall communications to or from the handheld application may be secured,e.g., encrypted, by one or more methods while traversing all or part ofthe communication path.

In block 800, according to an embodiment of the invention, the serverreceives a request for information about a patient. In an embodiment ofthe invention, the request may include an identifier that uniquelyidentifies the patient. In response, the server may retrieve a patient'srecords (or cause them to be retrieved), e.g., from a database managedby a database management system, in block 804. Once retrieved, theresponsive information may then be transmitted to the handheldapplication in block 808.

In block 812, the server or servers may receive information related to aprescription being generated, which may take the form of one or morequeries. For example, a server may receive a request for drugs thatmatch certain keywords or other search term, or a server may receiveinformation otherwise related to a prescription. It will be appreciatedthat such queries may, in an embodiment of the invention, correspond orbe related e.g., to, any or all of the information gathered by thehandheld application in blocks 412-418 of FIG. 4. The server or serversmay transmit requested or related information in response.

When the user submits the prescription in block 420 of FIG. 4, in anembodiment of the invention, the submission may take the form of one ormore additional queries to the server in block 812.

In an embodiment of the invention, one or more of the queries maycomprise information about the physical and/or logical location of thehandheld device. For example, a device may include a GPS receiver and beable to transmit GPS coordinates. Instead of or in addition to theforegoing, a device may be able to determine its position, e.g., bytriangulating based on the relative strengths of signals received fromnearby cellular towers. Other location-based services include methodswell known in the art, and a device in connection with an embodiment ofthe invention may use any technology and/or combination of technologiesavailable to it to determine its physical location.

A device may also be considered to have a logical location based on itsparticipation in one or more LANs. For example, a Wi-Fi™ network may usea SSID to identify itself. In an embodiment of the invention, a handhelddevice may transmit the SSID in one or more queries to indicate, e.g.,to the server, which LAN the device is using. While identifying the LANmay not suffice to locate the handheld device precisely, thisinformation may in an embodiment of the invention be used to identifyresources (e.g., printers) that may be relatively near and/or accessibleto the user of the device.

In block 816, the submitted information may be validated. The nature andscope of validation may vary. For example, in an embodiment of theinvention, the server may check that the minimum information for aprescription has been provided and/or that all values are legitimate(e.g., that the specified pharmacy, drug, and/or form of administrationexist). If information is missing, inconsistent, or otherwise invalid,an error message may be transmitted to the handheld application in block820.

Validation in block 816 may go beyond that described above. In anembodiment of the invention, a server may make other checks. Forexample, the server may attempt to determine one or more of whether theprescribed dosage and/or frequency are consistent with therapeuticguidelines; whether the patient is taking one or more drugs that mayinteract adversely with the new prescription; and/or whether thepatient's records show an allergy and/or other medical condition thatmay be inconsistent with the prescribed drug, among other possibilities.The server in an embodiment of the invention may retrieve a formularyassociated with the patient, e.g., because the patient participates in aparticular prescription plan, and determine whether the prescribed drugand/or drugs that may be substitutable for it are listed on theformulary. The results of such determinations may be transmitted to thehandheld application, which may in an embodiment of the inventionpresent information about one or more of the determinations to thephysician. In response, the physician may, e.g., confirm or modify theprescription as entered and/or override prescription guidelines, amongother possible responses.

If the submitted information is valid and/or otherwise acceptable, theserver may then determine how to transmit the prescription forfulfillment. In some jurisdictions, for example, a prescription, e.g.,for some controlled substances, may not be transmitted electronically.In an embodiment of the invention, as FIG. 13 depicts, a server may inblock 824 determine whether a paper prescription with the physician'soriginal signature may be required. If not, the server may then furtherdetermine in block 828 whether a printed prescription has been requestedby the user.

If a prescription is to be printed, e.g., because it is required orrequested, the server may in an embodiment of the invention determinewhere to transmit information to cause the prescription to be printed.If it is determined in block 832 that a particular printer has beenspecified, e.g., in one or more of the queries received in block 812,that printer may be selected. If no printer has been specified, thenbased, e.g., on location information that may have been received inblock 812, the server may determine in block 832 whether a printer isassociated with the reported location. The specified and/or associatedprinter may be selected in block 836.

If no associated and/or selected printer is identified, the server mayin an embodiment of the invention select a default printer in block 840.

In block 844, a server may transmit information, e.g., to the printerand/or a print server associated with the printer. The information mayinclude, e.g., identification and/or authorization informationestablishing that the server has sufficient privileges to use thatprinter, commands to manage the printer, print server, and/or printingqueue associated with the printer and/or print server, and/orinformation and/or commands to direct the printer to print aprescription.

The nature of the transmitted information may vary in an embodiment ofthe invention. It will be appreciated that handheld devices and theiroperating systems may not include printer drivers, for example. In anembodiment of the invention, the server may have access to patterninformation, e.g., in the form of one or more templates for one or moredocuments and/or types of documents, or other information and/orinstructions that may be used to create a representation of a document.The server may use such pattern or other information to render thedocument into, e.g., a representation of the document in a pagedescription language such as PostScript®, PCL, XPS (or OpenXPS),Portable Document Format (PDF), etc. The information transmitted inblock 844 may in an embodiment of the invention be or comprise such arepresentation.

In block 848, the server may receive one or more responses from theprinter and/or print server that received the printing job. The servermay then in block 852 determine whether the response indicatessuccessful printing of the prescription or, alternatively, it maydetermine that the response indicates that an error occurred. If anerror is found, the server may in an embodiment of the inventiontransmit notification of the error to the handheld device, e.g., as inblock 820.

In an embodiment of the invention, if the response indicates successfultransmission and/or printing for the prescription, the server may thenin block 856 update one or more records, e.g., in the database, whichmay include records representing the patient's chart. The server mayalso in block 860 transmit, e.g., a confirmation message to the handheldapplication, which may in turn display, e.g., a confirmation message tothe user.

If a prescription is to be transmitted electronically, in an embodimentof the invention, the server in block 864 sends the prescription, e.g.,by communicating with one or more computer systems associated with thepharmacy or mail order fulfillment center or by generating, e.g., animage of the prescription and transmitting it electronically to thedestination. Upon successful transmission of the prescription, theserver may in an embodiment of the invention transmit confirmationand/or take other actions, e.g., as described above.

It will be appreciated that there are several ways, including those wellknown in the art, to associate a printer with a physical and/or logicallocation. For example, administration in an embodiment of the inventionmay be accomplished, e.g., through a Web-browser based interface to oneor more applications, e.g., using a Web server 344 (FIG. 3) and/orapplication server 348 (FIG. 3). For example, in an embodiment of theinvention, one or more printers may be associated with one or more usersand/or groups of users. Each respective printer may be associated withinformation that may include, e.g., the sizes and/or types of paper theprinter is to be loaded with, one or more types of documents that are tobe sent to the printer, and network information sufficient for theserver to contact the printer.

In an embodiment of the invention, a computer system, which may bephysically proximate to the printer, may serve as a print server. Thecomputer system may be configured, e.g., to receive print jobs, to queuethe received jobs, and/or to spool them to the printer. The print servermay in connection with an embodiment of the invention register itselfwith a server as a possible destination for print jobs, e.g., using anapplication and/or daemon installed on the print server.

In an embodiment of the invention, the print server may initiateconnection with a server that processes prescriptions, e.g., asdescribed above. For example, one type of connection, in connection withan embodiment of the invention, may be a persistent HTTP (or HTTPS)connection, in which a print server may establish a connection bysending an HTTP request including, e.g., identification and/orauthentication information, to the server. The print server may thenperiodically send a keepalive packet to the server to maintain theconnection. If a connection times out despite the keepalive packets, theprint server may reestablish the connection as required.

The server, for its part, may in an embodiment of the invention notrespond to the HTTP request or requests until a document is to be sentto the print server. The response in such an embodiment may byinformation that the print server may use to cause the printer to printthe document. The effect may be the same as if the server were to “push”the document to the print server or printer, even though the printserver may in a sense “pull” the document from the server.

In an embodiment of the invention, the location of the printer, e.g., astreet address, may be provided, e.g., through an administrative userinterface such as described above. When a prescription or other documentis to be printed, the street address may be used along with the locationinformation provided by the device, e.g., to select the printer nearestto the user that is configured to accept that accept the kind ofdocument for that user. Instead of or in addition to information about aprinter's physical location, information that identifies one or morenetworks, e.g., SSIDs, may be associated with one or more printers. Aserver may then in an embodiment of the invention send, e.g., all printjobs originating from handheld devices that participate in a networkwith a particular SSID to the printer registered with that SSID.

Printing of more than one kind of document and/or other information maybe supported in connection with an embodiment of the invention. Anapplication according to an embodiment of the invention may presentkinds of information and/or offer functions in addition to drug andprescription information and/or electronic prescribing. For example, thepatient summary screen 480 that FIG. 7 depicts lists several results 508of laboratory tests for the patient.

In an embodiment such as FIG. 7 depicts, a user may select a result,such as the result 512 of a lipid panel, and the result or results ofthe analysis may be presented, e.g., as a lab detail screen 900 such asFIG. 14 depicts. The lab detail screen may include results for one ormore analytes 920. In an embodiment of the invention, one or more of theanalytes 920 may be selectable, and selection of an analyte 920 maycause the application to present, e.g., more information (not pictured)about the test, analysis, and/or analyte.

The lab detail screen 900 may also include one or more buttons 924and/or other items 928 that, when selected, cause display of a fullreport. In an embodiment of the invention, a “full report” may be areport that in one or more respects resembles a printed report, or animage of such report, that may include, e.g., all information such asmay commonly be reported to the physician or other practitioner whorequested the test. FIG. 15 depicts a display screen 950 that includesan example of a first page 960 of a report, in connection with anembodiment of the invention.

It will be appreciated, however, that inconveniences may attend use of ahandheld device to review a full report such as FIG. 15 depicts in part.The iPhone® 3GS sold in 2009, for example, comprises a 480-by-320 pixeldisplay that measures 3.5 inches diagonally. Such a display may not bethe most convenient means for viewing a report that is formatted, e.g.,for one or more standard US letter- or A4-sized pages.

Accordingly, in an embodiment of the invention, a full report displayscreen 950, such as FIG. 15 depicts, may include, e.g., a button orother control 964 that may be used to request printing of the fullreport. As FIG. 15 depicts, for example, a button 964 labeled “AutoPrint” is provided. In an embodiment of the invention, selection of thebutton 964 may cause the handheld application to send one or morequeries to a server requesting that a full report be printed. Asdiscussed above in connection with printing a prescription, one or moreof the queries may comprise information that, e.g., identifies and/orauthenticates the user, device, and/or application, identifies one ormore lab reports that are to be printed, and/or includes locationinformation.

The server, receiving the query, may respond by, e.g., generatinginformation that may cause a printer and/or print server to print thereport, selecting a printer or print server to send the information to,and sending the information to the selected destination. As discussedabove, one or more document types may be associated with a printerand/or location; accordingly, in an embodiment of the invention, theselection of the destination printer and/or print server may be based inpart on the type of information and/or document.

Certain attributes that may be associated with one or more printersand/or print servers and/or used by a server to select a destinationprinter and/or print server are discussed above. Without limiting theforegoing discussion, attributes that may be considered in selecting adestination printer according to an embodiment of the invention mayinclude, for example, the type of document (e.g., prescription, medicalreport, etc.), the paper size and/or type upon which the document is tobe printed, the physical and/or logical location of the handheld device,the identity of the user and/or one or more groups and/or organizationswith which the user may be affiliated, the identity of the patientand/or one or more groups and/or organizations with which the patientmay be affiliated, one or more attributes of the information (e.g.,partial vs. final report, normal vs. abnormal test result, controlledsubstance prescription, etc.), among many other possibilities.

In an embodiment of the invention, the location information and/or oneor more specified attributes may determine the printer and/or printserver to which the document is sent, and in an embodiment of theinvention, such information may be used, e.g., to select one or moredefault and/or candidate printers and/or print servers, and the user mayselect, e.g., by using one or more display screens and/or user interfaceitems (not pictured) presented by the handheld application to select aprinter and/or print server. In an embodiment of the invention, the usermay be able to select a printer and/or print server other than a defaultand/or candidate printer and/or print server selected, e.g., by theserver.
